. . A stepper motor is being used as a crane motor in an expensive toy. The motor has the following properties: Holding torque = 35 in. oz, dynamic torque = 20 in. · oz, and detent torque = 5 in. · oz. The motor turns a 1.5-in. diameter pulley around which a string is wound. How much weight can the crane lift? How much weight can the crane continue to support with the power on; with the power off?
